California unveils ambitious climate plan

California on Thursday took a major step forward on its global warming fight by unveiling an ambitious plan for clean cars, renewable energy and stringent caps on big polluting industries.

The plan, which aims to reduce pollutants by 10 percent from current levels by 2020 while driving investment in new energy technologies that will benefit the state's economy, is the most comprehensive yet by any U.S. state.

It could serve as a blueprint not only for the rest of the United States, but also for other big polluting nations like China and India, planners and environmental groups said.

"This is of tremendous importance, not only for California," Mary Nichols, chairman of the influential California Air Resources Board (CARB), said on a conference call with reporters on Wednesday. "By taking action here ... we will be able to help motivate other states in our nation."

At a meeting in Sacramento on Thursday, CARB staff will present a series of proposals that would become law in 2012, with some measures going into effect two years earlier.

The initiatives include implementing a cap-and-trade program on carbon dioxide emissions that will require buildings and appliances to use less energy, oil companies to make cleaner fuels, and utilities to provide a third of their energy from renewable sources like wind and solar power.
